it is, or more exactly: it can be, but you have to understand how 
parallelism works and what you are doing

[Pw_forum] parallel computing for phonon calculations

2011-11-16 Thread Elie M

Dear all,
I am doing phonon calculations for a 60 Carbon atom Grain boundary system and I 
have got in total 180 irreducible representations which in fact take a lot of 
time and memory (this is if it was completed). Is it efficient to use parallel 
computing in QE for doing the phonon calculations? Any information on this is 
highly appreciated..
Thanks
